The situation when you go to the refrigerator Beko and discover that the food has begun to spoil, and there is room temperature inside, always causes panic. This is a serious problem that requires immediate intervention, since the safety of the food supply and the further fate of the unit itself depend on the speed of the reaction. Most often, owners are faced with the fact that the motor is running, but there is no cold, or the device is completely silent and shows no signs of life.
Before calling a technician or looking for the number of a service center, it is important to carry out initial diagnostics yourself. In many cases, the cause of the malfunction is simple things that can be easily fixed without special tools. However, there are also complex technical breakdowns associated with system tightness or electronics that require a professional approach.
In this article we will look in detail at why your refrigerator stopped freezing, how to distinguish a minor malfunction from a serious breakdown, and what you can do on your own. Understanding the principles of operation refrigeration circuit will help you save time and money, as well as correctly formulate the problem when talking with a specialist.
⚠️ Attention: If you hear a hissing or whistling sound coming from the back of the unit, immediately unplug the device. This may indicate depressurization of the system and a refrigerant leak.
Main reasons for the lack of cooling in the chambers
There are many factors that affect the efficiency of refrigeration equipment. Most often, the problem lies in a violation of heat exchange or failures in the control system. If the compressor is humming, but there is no cold, it may be that the temperature sensor has failed, which is sending incorrect signals to the control board. The thermostat may have failed. Another common cause is a clogged capillary tube or filter drier. A refrigerant circulates in the system, which changes its temperature when the pressure changes. If an ice plug forms in the circuit or moisture gets in, the normal circulation of freon is disrupted. As a result, heat is not removed from the chambers, and the products begin to deteriorate. thermostat or a temperature sensor that sends incorrect signals to the control board.

It is also worth considering the condition of the rubber seals on the doors. If they do not fit tightly, warm air constantly flows inside. The compressor is working hard, trying to compensate for the heat flow, but cannot cope with the load. In such cases, a “coat” of ice may appear on the walls, and the temperature in the main chamber will be higher than normal.
Diagnostics of the compressor and start relay
The heart of any refrigerator Beko is the compressor. If it does not start, there will be no cooling in any of the chambers. The first sign of a malfunction is often a characteristic clicking sound, followed by silence, or attempts to start that last a few seconds and stop again. This indicates problems with starting relay or the engine itself.
You can check the starting relay visually and by ear. If you hear a loud click when you try to start, but the compressor does not start, the piston may be jammed or the winding may be burned out. In some cases, the relay simply oxidizes or melts due to power surges in the network. Replacing this element is an inexpensive procedure and can often be done at home if you have basic skills.
If the compressor runs constantly without turning off, but does not create the necessary pressure in the system, this may indicate a loss of performance. The valves inside the mechanism could be worn out, and it simply “drives” freon in a circle, without providing the required pressure drop for effective heat exchange.
How to check the compressor with a multimeter?
To check, you need to ring the motor windings. Normal resistance between the contacts should be in the range of 10-30 ohms. If the device shows an open circuit (infinity) or a short circuit (zero), the compressor is faulty and requires replacement.
It is impossible to perform this operation independently without special equipment.
Problems with the refrigerant and the tightness of the circuit
One of the most unpleasant reasons for why the refrigerator Beko stopped freezing is a freon leak. The refrigerant is a working fluid that circulates through the tubes, taking heat from the chambers and releasing it to the environment through the condenser. If a fistula or crack appears in the system, the gas escapes and the cooling cycle is interrupted.
Leakage can occur anywhere: in the foam housing, in the evaporator or at the joints of the tubes. Often the cause is mechanical damage during transportation or metal corrosion. Signs of a leak are:
- 🧊 Complete absence of cold when the compressor is running.
- 🔥 Strong heating of the condenser grille at the rear (the compressor works without stopping).
- 💨 Traces of oil in the place where the tube is damaged (freon comes out along with the oil).
- 📉 A drop in pressure in the system, which is recorded only by a pressure gauge.
If you suspect a leak, under no circumstances try to simply “top up” the refrigerator. Without finding and eliminating the leak, freon will leave again in a short time. The technician must find the damage, solder it, vacuum the system and only then fill in a new volume of gas.
⚠️ Attention: Freon itself is odorless and colorless, but some of its types can form toxic compounds when in contact with an open flame. Do not use lighters to search for leaks!
Malfunctions of the defrosting system (No Frost)
In models with the system No Frost a frequent cause of lack of cooling is a failure in the defrosting system. An ice monolith is growing on the evaporator, which is hidden behind a plastic panel inside the freezer. This ice blocks the channels through which cold air should enter the main chamber.
Several elements are responsible for the defrosting process: heating element (heater), defrost sensor and timer (or electronic module). If the heating element burns out, the ice does not melt. If the sensor is faulty, it does not give a command to turn on the heating or, conversely, does not turn it off in time. As a result, the fan either stops due to ice or blows warm air.
For diagnostics you need to:
- Defreeze the refrigerator manually for 24 hours.
- Check the integrity of the heating element with a multimeter.
- Ring the defrost sensor and thermal fuse.
- Make sure that the fan rotates freely.
☑️ Diagnostics of the No Frost system
Often owners forget about cleaning the drainage hole through which water flows into the tray on the compressor. If it is clogged with debris or ice, water begins to accumulate at the bottom of the chamber and freeze, which also disrupts the operation of the system.
Failures in electronic controls and sensors
Modern refrigerators Beko are equipped with complex electronics that control all processes. If errors appear on the display or indicators flash, this is a direct signal of a malfunction. The control board may receive incorrect data from temperature sensors, which is why it does not turn on the compressor or fan.
Particular attention should be paid to the temperature sensor in the main chamber. If it “lies” and shows that it’s +2°C inside, when in fact it’s +15°C, the compressor simply won’t start. Replacing the sensor usually solves the problem. Failures in the control module itself are also possible due to voltage surges.
| Symptom | Possible cause | Solution method |
|---|---|---|
| Error F1 is on | Sensor malfunction evaporator | Replacing the sensor |
| The Super Freeze indicator is flashing | Compressor malfunction | Checking the start relay |
| No response to the buttons | Blocking or board failure | Reset |
| Continuous operation of the motor | Freon leakage or wear | Call a technician for diagnostics |
To reset the error, it is often enough to disconnect the refrigerator from the network for 10-15 minutes. If after switching on the problem returns, a more in-depth diagnosis is required.
The influence of external factors and operating conditions
Sometimes the reason for the lack of cold is trivial and is not related to the breakdown of parts. For example, if the refrigerator is located close to the wall, the radiator at the back cannot effectively transfer heat. The air stagnates, operating efficiency drops, and the compressor overheats.
It is also important to consider the room temperature. If the room is too cold (below +10°C), the oil in the compressor thickens and it may not start. If it is too hot (above +32°C), the system may not cope with heat dissipation. In both cases, the device plays a decisive role. Climate class Leave a gap of at least 5-10 cm between the back wall of the refrigerator and the wall or furniture for free air circulation. This will extend the life of the compressor. climate class devices plays a decisive role.
Frequently opening doors or placing hot food inside also creates extreme stress. In such cases, the refrigerator may temporarily stop coping, but after stabilization of conditions, operation returns to normal.
When you need to call a specialist
Despite the possibility of self-diagnosis, there are situations when you cannot do without a specialist. If you have checked the socket, relays and sensors, but the refrigerator Beko still does not cool, most likely the problem is in the sealed circuit or compressor mechanics.
Opening the foamed part of the case, searching for micro-leaks and professional refilling with freon requires special equipment: a vacuum pump, a pressure gauge station and scales. An attempt to do this “by eye” will only lead to damage to the equipment.
In addition, if the refrigerator is under warranty, any independent repair will lead to its loss. In this case, the only correct solution would be to contact an authorized service center.
Why does the refrigerator freeze but does not turn off?
This may indicate a freon leak, compressor wear, or a thermostat malfunction. The system tries to reach the set temperature, but due to a lack of refrigerant or low motor performance, this is not possible. Diagnostics of the pressure in the system is required.
Is it possible to operate a refrigerator with defrosting not working?
For a short time - yes, if you regularly defrost it manually. However, constant work with ice on the evaporator will lead to overheating of the compressor and its rapid failure. It is better to eliminate the malfunction of the heating element or sensor.
How long should the refrigerator cool down after defrosting?
Usually it takes from 2 to 4 hours to reach the temperature. If after 5-6 hours of operation of the compressor the chambers have not become colder, this is a sign of a technical malfunction, and not the result of defrosting.
